• 400 sq. miles, watershed is 6X’s that size• 4 major rivers: Hillsborough, Manatee, Little Manatee, and Alafia• Over 100 + creeks• Phytoplankton is the primary producer in the food web• More than 200 + fish species• 5 counties: Hillsborough, Pinellas, Polk, Pasco, and Manatee• 40,000 pairs of 25 different species of birds. Most diverse in N.
America• Average depth = 12 feet, largest shipping channel = 43 feet deep /
40 miles wide• More than 4 billion gallons of oil, fertilizer components, and other
hazardous materials pass though the bay each year.

• In the water / closest to the water• Really high prop roots / stilt roots= prevent erosion / provides stability• Thick leaves reduce water loss• Seeds are long, pencil shaped seedlings called propagules.
• More like a bush•Between the red and white mangroves• Fingerlike projections that stick up out of the sediment are called pneumatophores. They serve as a ventilation system.• Salt glands on the surface of the leaf that secrete salt. The leaves glisten.• Seed = fruit embryo
• Looks more like a tree• Grows higher in elevation by land• No visible root system• Two visible salt glands at the base of the leaf•Yellowish / green leaf• Seeds look like a sunflower seed.

• Have to be exposed to air• Experience high salinity levels due to the intertidal exposure• Biological filters for terrestrial run-off• Grow in anoxic sediment (low oxygen) and have to tolerate
higher levels of salinity due to evaporation• Facultative Halophytes= tolerate SW and FW conditions.• Importance:
– 1. Refuge, feeding ground, hiding spot– 2. Nursery– 3. Detrital food chains– 4. Stabilize sediments to prevent erosion– 5. Recycle phosphorus, filter run-off (remove toxic organic
pollutants)

Physical Structures:- Grow in tufts of vertical stems connected by rhizomes.- Vertical stem= culm, which produces additional stems called tillers (format the base making it look bushy)- Roots are at the culm- Rhizomes-> connected root system- Leaves have a thick cuticle to slow water loss- Highly developed vascular system for efficient transport of water- Leaves- have salt glands= secrete salt to the outside, which prevents salt toxicity

• Spend about 8 hours a day eating• They eat FW and SW plants• During the cold winter months they migrate to warm waters (ex-
power plants and springs)• Use its flippers and tail to steer itself through the water and moves
its tail up and down to move forward (FWC, 2014). They can do somersaults, rolls, and swim upside down
• Surface to breathe every 5 minutes. Can hold their breath for 20 minutes (during resting)
• 13 month gestation period• Six cervical vertebrate, most mammals have seven. They can’t turn
their heads sideways, instead they must turn their entire body.• Information from TBEP.org and myfwc.com
